Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Malacanthidae (Tilefishes) > Latilinae
Etymology: Branchiostegus: Greek, brangchia = gills + Greek, stego = roof, to cover (Ref. 45335);  saitoi: A new species of Branchiostegus was first caught off Batangas Laiya, Philippines in 2009, photographed and eaten. Two years passed before two more specimens were caught by J. Saito, an amateur angler from Japan in April, 2011. Without J. Saito’s considerable efforts and interest, this species would have remained unknown. The new species is herein named in his honor (Ref. 89848).

Environment / Climate / Range Ecology

Marine; benthopelagic.   Tropical, preferred ?; 14°N - 13°N, 121°E - 122°E

Pacific Ocean: Philippines. Known only from Bayangas, Laiya at 210-220 m depth, it is possibly endemic; but as it is very rare, and probably inhabits burrows as do other tilefishes, B. saitoimay ultimately be found at other localities (Ref. 89848).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 32.9 cm SL male/unsexed; (Ref. 89848)

Short description Morphology | Morphometrics

This species can easily be distinguished from its congeners by the following combination of characters: a great body depth (28-29% SL; other species usually 27% SL) longer head length (30-31% SL; other species usually 28%), head profile oblique, about 130 degree angle (other species usually 95-130 degrees); head depth (26-27% SL; other species usually 26% SL); eyes high on head (interorbital width 31-34% HL); small orbital diameter 24–25% HL, only B. sawakinensis and B. albus with small orbital diameters, 23-24% HL) long predorsal length (35% SL; other species usually 30–32% SL, rarely 33-34% SL), deep body (28-29% SL; other species usually 24-27%, rarely, only in B. japonicus and B. semifasciatus, 28-29% SL); wide body (14-15% SL; other species usually 11-13% SL); number of first arch gill rakers low 18 + 1 rudimentary, most other species 18–24, modally 19-22 (Ref. 89848).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00298 - 0.01684), b=3.07 (2.86 - 3.28), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100) .
